PULL-CHAIN GUIDE.

Application filed September 1, 1911. Serial No. 647,300.

To all whom it may concern:

Be it known that I, EDGAR H. l nnmnm, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Pull-Chain Guides, of which the following is a specification.

This invention relates to chain guides for electrical pull sockets, and has in view an improved construction of guide possessing all of the characteristics and functions of the conventional one-piece pull chain guide or horn, while at the same time providing means whereby the main guiding member or bell may be readily and conveniently handled for reburnishing purposes.

- A further object of the invention. is to provide an improved pull chain guide which is in the form of an attachment to the shell member of the socket casing, and is held in operative position by the socket cap when placed in position. In this connection the invention also contemplates a guide attachment which is readily and freely detachable from the shell member of the casing, so that the switch mechanism can be readily handled in being inserted and removed from the casing without interference from the chain.

With these and other objects in view, which will be readily apparent to those skilled in the art, the invention consists in the novel construct-ion, combination and arrangement of parts hereinafter more particularly descri ed, illustrated and claimed.

While susce ible of embodiment in various ways by t e use of different mechanical equivalents, the invention is exemplified by the preferable form thereof shown in the accompanying drawings, in which- Figure l is an external view of an electrical pull socket casing fitted with a pull chain guide constructed in accordance with the present invention. Fig. 2 is a vertical sectional view illustrating the v Improved guide in its operative relation to the socket casing, and to the pull switch therein. Fig. 3 is an enlarged cross-sectional view on the line 3-3 of Fig. 1. Fig. 4. is a detail in pers ective of the guide and the part of the shell to which it is detachably applied.

'Like references designate corresponding parts in the several figures of the drawing.

The guide body may be of any suitable form or configuration. However, it is preferably of the usual horn or bell type, so that the same may be said to consist of a onepiece bell-member designated by the numeral 1, and having the outer flaring mouth and an inner reduced neck part. Accord- 1ng to the present invention the inner reduced neck part oi. the guide body or hellmembcr l is rigidly united, in any suitable manner, to an attaching plate 2. This attaching plate may be of any suitable size or shape, but is preferably of a general rectangular form to provide a supporting member or base that carries the guide body or bellmcmber and permits its ready attachment to and detachment from the socket casing...

To provide for the proper mounting of the guide attachmcl'ia it is preferable, in carrying out the present. invention, to provide a slidable interlockingcohncction twecn the attaching plate 2 and the shell 3 of the socket casing, said casing also including the usual cap 4 that is fitted to one end of the shell. This slid'able interlocking engagement between the plate 2 and the shellmember 3 of the casing may be accomplished in various ways, but a practical method is shown in the drawings and consists in constructing the plate 2 at opposite side edges with spaced flanges or equivalent elements 5 which form therebetween retaining grooves which engage over or receive the opposite side edges of a resilient slot 6, formed in the shell 3, and opening through one edge thereof, said slot being disposed longitudinally of the shell and corresponding to the usual key slot' with which the casings of key sockets are ordinarily provided. It will thus be seen that by shdably interlocking the plate 2 with the edges of the slot 6, the said plate may be moved to a covering position over the slot and held there by the attachment of the ca 4 u on the shell 'In this position the guidh bo y or bell-member 1 receives and guides thercthrough the usual pull-chain 7 of the nil-switch S, carried by the switch body B ocated in the socket casing. It will also be apparent that upon the removal of the socket cap, not only the switch is freely accessible and removable, but also the guide attachment may be quickly and easily removed for reburnishin'g purposes, and also to facilitate the removal of the chain if necessary.

In the foregoing description, the principal member 1, the attachin plate 2 and the holding elements 5 have lieen referred :to in ageneral way, but from a manufacturing standpoint the several parts are preferably .5 constructed and arranged as shown in the 15 provided at'its outer edge, with an edge flange 8 that is clenched over the outer end of the sleeve 7 I claim:

A pull chain guide comprising an outer sleeve-member, a bell-member proper nested 20 within said sleeve member, said sleeve and bell-members beingprovided at their inner ends with flanges spaced apart to provide retaining means for the guide.

In testimony whereof I hereunto eilix my 25 signature in the presence of two witnesses.

- EDGAR H.- FREEMAN.
